What happened to Magic Pie 2...
« on: June 18, 2014, 10:40:07 AM »
I need a new project, and allready have a front Magic Pie 2.

Case is, I have two spare controller cards and two programming cables  :P

Now I want to make my 2nd bike... with rear motor. Anybody knows where I can get my hands on a 28" MP2?

Because then I could use my spare parts...  ;)

For the new project, I bought this battery... problem is when I google the brand it says stay away...  :o but the stay away post was from 2009. Maybee they have fixed it... if I ever get it I will post a review.

If you're using it with a Magic Pie I would be concerned about the low current output for a 15Ah pack:

Rated Discharging Amperage:   ?12 Amps

The power output socket is the same as mains power leads which could make it illegal to use in many countries.
I don't even want to think about what could happen if a 240v mains supply power lead was inadvertently plugged straight into the battery's output socket.

I know, but my Magic Pie is adjusted to max.20A peak, so it should be ok. Before I adjusted it down from 35A the BMS kicked in on my existing 48V 10Ah lithium, rated at 15A. Works sweet now on 20Ah. If I used it in hilly terain with heavy wind with cold battery the BMS gave up before I entered max current to 20A. But I don't believe in all the numbers when they advertise. Maybe the weight is correct and gives an indication of capacity. When I get this pack I will test the Ah after some charge cycles, also open case and improve it, install melting fuses etc. But surface post is slow...

Haha, these chinese manufacturers don't follow EU regulations  ;D

On the first battery pack I bought, the was no fuse on main cable, nor a fuse on the charging wire. In case the electronic fails, there should allways be a melting fuse.
So I installed a 20A car fuse on main wires, and a 2A fuse on the charging lead. Safety first  :)

For the plug... I think I will remove it, better to just have the cable connected directly trough screw terminal block or WAGO. A plug seems silly, it will probably fall out when you hit some bumps  ::)
